IMPROVEMENT lN COMBINED STOVE AND HEAT RADIATORS.

Specification forming part of Letters Patent No. 165,597, dated Ju y 13,1875; application filed March 6, 1875.

To all whom it may concern Be it known that I, NEWTON H. LENHARR, ofWhite Pigeon, in the county of St. Joseph and State of Michigan, haveinvented an Improvement in a Combined Stove and Heat Radiator, of whichthe following is a specification:

My invention has for its object to so construct a heating-drum as thatit can be disconnected from the stove-pipe and used as a heating-stove,and it consists in the novel and peculiar construction of the device, asmore fully hereinafter set forth.

Figure l is a perspective View, with a por tion of the shell broken awayto show the interior arrangement. Fig. 2 is a vertical section. Fig. 3is a plan with the top or covering-plate removed.

In the drawing, A represents a sheet-metal shell, which forms the bodyof the stove and radiator, having a bottom, B, and cover or cap 0. Inthe center of the bottom there is a socket, b, to receive a stove-pipewhen used as a radiator to warm an upper room. 0 is a pipe-collar in thecap, on which the smokepipe is sleeved. B is a false bottom in the lowerpart of the shell, and G is a false top, thereby making shallow base andtop chamhers, which are connected by a flue, l), on the inside of theshell. F is a curved flue-strip in the base chamber, and F is a similarone in the top chamber. a is a door in one side of the body, with adraftregister below it. (Not shown.) d is a damper pivoted to the plate0 on its upper side, adapted to swing overasmoke-hole, e, in said plate,it being operated by a rod, f, passing through the shell. When used in aline of stove-pipe as a heat-radiatr r, the door and draft-registershould be closed, and also the damper. The smoke and heated currentsenter the base-chamber, pass around the flue-strip F, thence up throughthe flue D into the top chamber, where they pass around the flue-strip Fbefore finding an exit at the pipe collar, whereby a great portion ofthe heat is absorbed and utilized by radiation from the large surfaceover which the said currents pass.

When used as a stove, the pipe-socket at the bottom may be closed by asimple stovepipe stopper, when a fire can be built in the principalchamber, the damper d first being opened the smoke and gases will passup through the hole 6 around the flue-strip F, and thence through thepipe into the chimney.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the shell A, bottom B, top 0, partitions B O, flue D,flue-strips F F, door a, socket b, collar 0, damper d, and smoke-hole c,all constructed and arranged to operate as described.
